KAT500 Problem --- switching antennas
 
|
Ever since the most recent KAT500/KPA500 firmware updates, switching between antenna 1 and 2 shows funny behavior.
For example, on the 20 meter band I have two antennas: Antenna #1 -- Wire 80-meter Dipole (ladder line fed) Antenna #2 -- Hex beam So, I am positioned on antenna #2 for 20 meters. I switch manually with the KAT500 to antenna #1. This works fine. Then, when I switch from #1 back to #2, the KAT500 briefly goes to #2 enough to light up the #2 LED but then immediately bounces back to #1. Now, if I switch again from #1 to #2, there is no bounce back and everything is fine. This problem is totally repeatable. Always on a bounce the first attempt to return to #2 from #1 but the second time (done immediately) works fine without problems. Anyone else see this behavior. 73, phil, K7PEH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

More experimenting this afternoon...
I am pretty sure now that it is the switch itself. If I do a press and hold (as if it had one of those famous hold functions) then the switch operates just fine. No problems. But, if I press as pressing a normal switch like I do a hundred times a day on the Elecraft gear (OK, maybe 30 times a day) then at times (more than half) the switch bounces back. But, it is strange that this behavior started right after I upgraded firmware to 1.63. I mean, the entire time I have had the KAT500 I have not had a problem with this switch until after the upgrade. So, if I were to assume wild things I could assume that the timing has changed a little bit on these button pushes. Maybe the software used to detect a button press faster than it does now or something like that. Not sure. But, the other antenna LED does briefly flash on before it bounces back. So, maybe it is a physical problem with a double hit on the switch itself. Just wild guesses here. I have done some PIC coding before with switch sensing so I understand that this could be an issue but then again, maybe just a funky switch. 73, phil, K7PEH On Apr 13, 2014, at 4:15 PM, Cady, Fred <[hidden email]> wrote: > Not seeing it here, Phil. > KAT firmware 1.63 > 73, > Fred KE7X > > >> -----Original Message----- >> From: [hidden email] [mailto:elecraft- >> [hidden email]] On Behalf Of Phil Hystad >> Sent: Sunday, April 13, 2014 3:02 PM >> To: Elecraft >> Subject: [Elecraft] KAT500 Problem --- switching antennas >> >> Ever since the most recent KAT500/KPA500 firmware updates, switching >> between antenna 1 and 2 shows funny behavior. >> >> For example, on the 20 meter band I have two antennas: >> >> Antenna #1 -- Wire 80-meter Dipole (ladder line fed) >> >> Antenna #2 -- Hex beam >> >> So, I am positioned on antenna #2 for 20 meters.

Same FW here...I can confirm the "dicky" switch action also and this has
been going on since the upgrade but not before. Easily repeatable here too.

Check to see which antennas are enabled for that band via the utility. I have 3 antennas and have them set for auto select only on specific bands. If I try to use my dipole (antenna 1, which WILL tune) on 15 meters by selecting the antenna (it's not enabled on that band, only the tribander - antenna 2) I get the same results you do. You will have to (via the utility's configuration tab) enable the antennas you want along with the band(s) you want them on before you can have it work the way you want. You might also have to select the "Last Used" click box as well.

If you are sure it's related to a firmware update,
can you revert to earlier firmware to confirm?

From our KAT500 Utility author Dick Dievendorff:
=== "If you have [KAT500] firmware version 1.63 and "sleep when Idle" on, that combination has a switch problem that has been corrected in Beta firmware version 1.67, available on our web site. ... We're probably going to put 1.67 into production early this week." ==== 73, Eric elecraft.com On 4/14/2014 7:45 AM, Phil Wheeler wrote: > If you are sure it's related to a firmware update, can you revert to earlier > firmware to confirm? > > Phil W7OX > > On 4/14/14, 12:47 AM, Gary Gregory wrote: >> Same FW here...I can confirm the "dicky" switch action also and this has >> been going on since the upgrade but not before. >> Easily repeatable here too. >> >> Gary ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
